Sculpt for glasses nosepads
Starting with the basic shape of the eyeglass frame. 
I started with a circle with 64 vertices and formed that to the inside of the frame and then extruded that out and shaped the outside of the frame. 


Then extruded that shape up to create the thickness of the frame. (I also used a Mirror Modifier and a Sub Surf Modifier).


I then selected the vertices that would make up the nose piece and pressed CTRL + “I” to inverse the selection. Then pressed “H” to hide that.


Then selected the following eight vertices and turned on Proportional Editing “Connected” choose “Sharp” for the falloff and pressed “G” and moved them up.



Then changed the falloff to “Linear” pressed "S" and scaled them in. 


You can press ALT + “H” to unhide the rest of the vertices and/or Tab into Object Mode to see the result.
